Temperature dependence of energy transfer fk-om the long wavelength antenna BChl-896 to the reaction center in Rhodospirillim Rubrum, Rhodobacter Sphaeroides (w.t. and M21 mutant) fk-om 77 to 177 K, studied by picosecond absorption spectroscopy. 

Moreover, temperature dependence of energy metabolism could be investigated with the setup described in section 3.4. It rendered the known parabolic behaviour of heat production rate as function of temperature with a maximum around 32 °C. Due to aerobic metabolism in the closed vessel the oxygen concentration dropped permanently. Lizards were able to cope with these changing conditions when longer lasting periods below 9.3 kPa p02 were avoided [83].

In principle, the reaction cross section not only depends on the relative translational energy, but also on individual reactant and product quantum states. Its sole dependence on E in the simplified effective expression (equation (A3.4.82)) already implies unspecified averages over reactant states and sums over product states. For practical purposes it is therefore appropriate to consider simplified models for tire energy dependence of the effective reaction cross section. They often fonn the basis for the interpretation of the temperature dependence of thennal cross sections. Figure A3.4.5 illustrates several cross section models.

Liquid Third Phase. A third Hquid with coUoidal stmcture has been a known component in emulsions since the 1970s (22) for nonionic surfactants of the poly(ethylene glycol) alkylaryl ether type. It allows low energy emulsification (23) using the strong temperature dependence of the coUoidal association stmctures in the water—surfactant—hydrocarbon systems. 

In connection with the earlier consideration of diffusion in liquids using tire Stokes-Einstein equation, it can be concluded that the temperature dependence of the diffusion coefficient on the temperature should be T(exp(—Qvis/RT)) according to this equation, if the activation energy for viscous flow is included.
